Record-breaking multiple F1 world champion Michael Schumacher has said it is almost impossible to say how Mercedes will go this weekend at the British Grand Prix.
Schumacher has yet to really get to grips with the sport since opting to come out of retirement this season and following a dismal showing in Canada, he struggled once again last time out in Valencia.
Indeed in the end he failed to make it through to Q3 and the top-ten shoot-out for pole and in the race finished a lowly 15th, his worst finish of the year.
Despite all that though, he insists he is still looking forward to the tenth round on the F1 2010 schedule, even if he is still trying to get to grips with the latest Bridgestone tyres.
"Silverstone represents a special race for us as it is so close to everyone at our factories in Brackley and Brixworth who are all working like hell to make up the quite difficult start into the season that we have experienced," Schumacher said. "We would like to give them and all of our supporters a good performance this coming weekend, even if we seem to struggle a bit at the moment.
"We have to face the fact that we were less competitive in Valencia than we had hoped for which makes it difficult to predict how we can perform at the British Grand Prix. Our race pace has been quite promising but our qualifying speed is not yet ideal and we still do not understand the full picture about the tyres. This clearly is something that we will keep working on intensively.
"I have a lot of different and mostly nice memories of Silverstone and therefore I am obviously very much looking forward to travelling there. We will certainly try to do our best there," he added.
Mercedes GP boss, Norbert Haug meanwhile added that a good result is crucial after the woe in Canada and Spain.
"The race at Silverstone is a classic and it is good for F1 that this traditional Grand Prix has remained on the calendar," Haug said. "After substantial modifications to the circuit, parts of the track layout will be new for all teams and drivers. With the remodelling, there are slower sections added to the predominantly fast layout of the track.
"Our Mercedes GP Petraons team will have two of our home races in a row this month with the German Grand Prix following just two weeks after Silverstone. It is very important for us to show an upward curve of performance this weekend though as we did not achieve the best possible results for us in the two previous races in Montreal and Valencia.
"Our hard working and totally motivated team will be giving their all for these improvements."
